The lead scientist monitoring St Vincent and the Grenadines’ La Soufrière volcano, Professor Richard Robertson, has said today’s swarm of volcano-tectonic (VT) earthquakes is an indication of magma trying to escape out the vent.
He made the comment in a video update provided by the University of the West Indies Seismic Research Centre (UWI-SRC).
“VT earthquake activity is one of the signs that we look for [as] an indication that this volcano is wanting to go to an explosive activity,” Robertson said.
He said it is important that residents in the danger zones not panic but be prepared to leave their communities once an order is given.
This is the second swarm of VT earthquakes to occur at La Soufrière within a month.
Since 6:30am, the earthquakes have been occurring at a depth of six kilometres below La Soufrière’s summit.
The largest quake had a magnitude of 3.5.
Robertson said this kind of activity at La Soufrière can occur as the volcano continues its effusive eruption.
